SimonDev (Simon Schreibt is a different person) is the YouTube channel and paid-course brand of an independent game and graphics developer — focused on the math, shaders, and Three.js / WebGL work that anchors modern interactive 3D in the browser. The channel has built a reputation for unusually deep treatments of computer-graphics fundamentals.
His CourseFlix listing carries three SimonDev courses: Three.js & GameDev, GLSL Shaders from Scratch, and Math for Game Developers. The teaching style is rigorous about the underlying math (linear algebra, trigonometry, calculus applied to graphics) that most graphics tutorials skip.
Material is paid and aimed at developers ready to study computer graphics from the foundations rather than copy shader recipes. For broader content, see CourseFlix's Three.js, Game Development, and Compilers & Interpreters category pages.
